ELECTRICAL INSTALLATIONWe recommend a qualified electrician perform the needed electrical connections to ensure proper operation of the scoreboard. These connections include connecting the scoreboard to a power source, installing the ScoreLink 200 or the control cable, and connecting the control console. The installation of goal lights and multiple scoreboards is also described in this section. Power Connection The scoreboard requires 120 VAC service at the scoreboard to operate properly. Maximum power consumption of Model 8850: 216 Watts. The scoreboard has a 6 ft. attached power cord located at the top of the cabinet. Plug the power cord into a grounded NEMA 5-15R receptacle. The receptacle should be controlled by a separate circuit breaker so that the scoreboard can be turned off without turning off other electrical devices in the facility. Figure 2 shows the electrical connection points on the scoreboard.
The SCORELINK 200 RF MODEM SET is intended to eliminate the control cable between the scoreboard and the control console on Electro-Mech Scoreboard MM and MP series scoreboards as well as all LED scoreboards. If you have purchased this accessory, disregard the section of this manual titled Control Cable Installation. Refer to the SCORELINK 200 RF MODEM SET OWNER’S HANDBOOK for installation instructions. Control Cable Installation The control cable connects the scoreboard to the control console. A small junction box with a ¼” stereo jack mounted on the face plate is attached to the control cable at the point of operation of the scoreboard. This junction box should be securely mounted within ten feet of the rear of the control console. Most customers order the control cable with the junction box attached. Some customers prefer to attach the junction box after the cable is installed. Those customers must solder the control cable to the ¼”stereo jack. Figure 3 shows the control cable wire connection points on the rear of the ¼” stereo jack.
A ¼” stereo plug is attached to the scoreboard end of the control cable. It is inserted into the ¼” stereo jack mounted on top of the scoreboard. Most customers order the control cable with the ¼” stereo plug attached. Some customers prefer to attach it after the cable is installed. Those customers must solder the ¼” stereo plug to the cable according to the figure 4. Unscrew the stereo plug cover from the plug body to expose the contact pins.
Control Console Connections The 10 ft. extension cable has two molded ¼” stereo plugs attached to it. It is used to connect the control console to the junction box. The following steps describe how to connect the control console:
This product is equipped with a 3-wire grounding type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact a qualified electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding-type plug. Goal Lights Installation This scoreboard can control a set of goal lights. The following steps describe how to install a goal light:
Installation of Two or More Scoreboards at the Same Site It is possible to operate multiple scoreboards or shot timers from the same console. Either install a control cable between each unit and the control console or install a ScoreLink 200 Transmitter at the control console and a ScoreLink Receiver at each scoreboard or shot timer. Additional scoreboards and shot timers can be controlled by connecting a control cable from the serial data output ¼” stereo jack on the right side of an installed scoreboard cabinet (figure 2) to the serial data input ¼” stereo jack on the top of the additional scoreboard or shot timers. Attach ¼” stereo plugs on each end of these cables according to figure 4. Never splice the control cables together or connect them to the same junction box. Each scoreboard will need to be connected to 120 VAC service.
